答复: Re: [squid-users] Can squid cache dynamic pages?

I find a method to cache dynamic pages in squid 2.4Stable.
I do it by modifying 'refresh_pattern' in squid.conf file:
     refresh_pattern .jsp 5 20% 20
In this way, squid can cache .jsp?xxxx in the memory. For the second time I
request that url, the access.log shows TCP_HIT.
